METHOD AND MEANS FOR THE MANUFACTURE OF WIRE-GLASS- Specification of Letters Patent. Application filed November 23, 1906. Serial No. 344,711.

)Eatexzrtecil April 9, 1907.

To all who/n if 71m concern; Be it known that we, human T. CARTER i and DANIEL S. BEEBE, citizens of the United States, residents of Beaver, in the county of Beaver and State of Pennsylvania, have invented or discovered a new and useful Method and Means for the Manufacture of ire-Glass, of which the following is a full, clear, and exact description, reference being had to the aeconmanying drawings, forming part of this specification, in which Figure] is aside view and partly in section of the apparatus employed with the table partly broken away. Fig. 2 is a plan view of l the same. Fig. 3 is a longitudinalsection on l the'line Ill ill of Fig. 2, but showing the i glass on the table. Fig. 4 is a transverse sec- .tion on the line IV IV of Fig. 2 with the l forming-tool in ele 'ation, and Fig. 5 is a detail view showing a modification. I The object of our invention, generally I stated, is to produce wire-glass by forming two layers or sheets-and embedding a wire i trellis between them during the forming off the second layer. I It further consists in pouring a batch of molten glass upon a table, and preferably; rolling a portion thereof into sheet term, i then placing one end of a wire trellis on the partly-formed sheet, then pouring a second batch on the wire and sheet, then by advancing a scraper into ei-igagcnnint with the batch l (which scraper has a portion of its side,the part that comes in contact wit h the batch, at l substantially an acute angle to the sheet to l l he formed) the portion of the batch that is above thelower edge of the scraper is forced forward and downward, thus covering the trellis with glass in advance of the and through the meshes of the trellis covering the partly-formed sheet. The scraper also in its forward movement exerts a downward pressure on that portion of the batch which is in close proximity to its forming edge, so that as it passes over the batch the batch is compressed, thereby completely tilll ingthe meshes of the trellis and compacting I l the partly-rolled sheet, trellis, and batch into an integral sheet.

Our invention also consists in several features of construction, arrangement, and coml bination, all substantially 'as hereinafter described, and pointed out in the appended claims.

In the accompanying drawings the nu-l meral 2 designates the ordinary table, such I moved vertically by means of adjusting- 7 for the purpose of varying the disupper surscrews tance between the roller 5 and the face of the table 2, according to the thickness of the glass sheet or layer to be formed.

8 designates the usual shoes or guides, which fix the width of the sheet and which are pushed ahead by the roll.

S) designates a scraper, which in the arrangement shown is located at the rear of the roller 5 and which is used to form the second or upper layer of glass. This scraper may be of various forms; but it consists, preferably, of a transversefv-extending bar having a convex spreading edge 10. 111 the form shown in Fig. 3 this bar is shown as having three convex spreading portions 10, any one of which may be used, so that if the glass sticks or burns to one of them it inav be readily turned to bring another into position for use. The scraper is normallyprevented from turn ing by means of the extensions 11 of the shoes or guides 12, which precede the scraper. The scraper pushes the shoes or guides 12 ahcadofit.

The scraper 9 is formed at each end with projecting shaft or spindle portions 9, and upon each of these is loosely mounted a sleeve 13, carrying a union-14, whose teeth engage the racks 3. Loosely mounted on each of the shaft or spindle portions 9 is also a wheel I5, which arranged to travel on a strip 16 at the edge of the table just inside of the rack 3. This strip maybe adjusted vertically, or it maybe removed and one of different thickness used to compensate the vertical adjustment of the racks 3.

17 designates hand-wluiels, which are mounted on the sleeves 13 and which are preferably used for the purpose of moving the scraper and for applying the necessary pres- I sure thereto.

lb designates achuto or trough through which the wire is fed upon the table 111 ad- 3 ,vancc of the scraper, as indicated in Fig. 3.

It) indicates the wire, which is fed to the table intermediate the roller and scraper throu h the chute 1S.

In the modification shown in Fig. 5 the 1ng a convex spreading edge 9 shafts r spindles of the roller and scraper.

The forward ends of these bars are formed with elongated cut-away portions or recesses 21 for engagement with the spindles of the roller in order to permit a limited movement of the roller before its forward motion will be transmitted to the scraper through said bars.

The operation is as follows": A batch of glas's'is placed upon the table in front of the roller 5. T he roller is'then actuated to roll down .and. spread, preferably, a portion oi the first batch into a sheet. The end of a wire trellis 19 is then placed. on the partly-rolled sheet. A second batch. is then placed on or in close proximity to the end of the partlyform ed sheet, so as to cover the end of the trellis, and as soon as the spindles of the roll engage the forward wheels of the recesses 21 the s'crarmr 9 also moves forwardly and its side, which at substantially an acute angle, engages the batch, compressing it, so that it gradually passes under the scraper, the lower edge of which scrapes it into an even and smooth surface layer, which is firmly united to the lower sheet or layer upon the embedded intermediate wire. The lost movement which. is provided by reason. of the recesses 2] enables the operator to insert the wire and the second batch. ol glass alter the formation of the first sheet or layer has commenced and before the scraper com-- mences to operate. Instead of the second batch being placed after the first sheet has been partly formed it can be placed on the table before the initial forming of the first sheet.

If desired, the roll and scraper may be disconnected and separately operated, the hint sheet or layer being completely formed before the formation of theseconrl one is commenced.

If desired, the roll and scraper or either of them may be cooled by circulating a cooling medium therethrough. I

Various changes may be made in the details of construction and arrangement without departing from the spirit and scope of our invention, the salient feature of which in the apparatus consists in the use of a scraper for forming the upper sheet or layer.
